WINDOW .sAsir Application filed July 23,

To all wIlL-0m 'itemciyfaoncem:

Be it known that I, VVILLLAM' STRANG, a

ot Chicago,`in the county of Cookand State voi'illlinois, have invented a new Improvement in 'Vindow Sashes, `of which the following-is a'i'ull', cleaigand exact description.

My invention relates to-ffiniprovements in windowsashes, and it consists .in'thecombinations,` constructions, Sand arrangements herein described 'and claimed.

' An object of my invention is' to fprovide a. window sash'ot the character .described in which the yglass is held on an'inner yframe hingedly mounted to 1 an outerframe and.- arranged to slide in1 the ordinary `type ofwindow frame, so that the inneri'rame may be hinged inwardly and both' suriacesfoiilthe Ar1923. Serial N0.i653,275.

#features of-A the invention fwill= be particublarly pointed-out fin the appended claim.

UiiitedfStates,aiid a resident My :invention i is illustrated in `the accom- -pa'nying drawings, forming part'ot' thisap- :and useful plication,y in which- Figure l is aifront elevation'of an embodi r`ment 'ot' -my invention,

"igurer 2 is ansectional view along the Aline 9,;2 of Figure. l,

FigureA a is an enlarged sectional view along the 'line 9i- 320i *.Fig'ui'el, and

Figure 4 is'anenlarged'sectional view 4along thefline 4-4 of'Figure l.

' In ca ryingout my invention, I make use of-.the ordinaryvtype of window'frame (not shown) in which a sash bearing awindow pane is Ynormally employed. f Thislordinary .type fof sash Ireinovel and substitute asa-sh 4trame. This sash frame lis provided with glass-rendered accessible' without' lthe.:aieces 1 sity ot' raising the ent-ire sash-asini theicase of the ordinary window.

The advantage' gained structure is: that the possibility of one 'falling from the window while washing the u-glass onthe outside is 1 entirely-precluded,

since this process maybe carrier onent-irely within.A the roo-ml where 'ordinarily 1 only.V the innerv side of the window pane isfaccessible.

ai; rabbeted portion '2201i thezout'er edge :of the lower wall thereof, and aiabbeted' portion "on the. inner; side vot its yupper wall. yin providing rsuch The vtwoside.walls 4 of the frame rare v'also provided with -rabbetedlportions on their inner edgesm'erging with the-:rabbeted -p'ortion 3v-on' theupp'er' wallffof 'the frame.

A further object off my invention-is Lto1 provide ai device of the 'character described f in which means is vprovidedfor limitingsthe A movement `of the inner frame oftheffs'ash so 'that the inner rame'inay notmove'fon its hinged support' into engagement withliobthe glass might becomebroken.

A further object of my invention is to provide a. device of thecharacter described in which theA abutting surfaces Vofthe' 'inner frame and the sash'are thoroughly waterproof so that water may. not enter through `the sash'whenv the window isproperlyelosed.

A further 'object of Amyuinvention is to provide a Inovel locking Lnreans :for locking the inner 'trame intoclose 'engagement 'with the sash.

A further object of my invention is to provide a device of the character described which may be used to replace the ordinary type `of window sash and in which no special tools or instruments are required to open or close the inner or glass carrying trame thereof. y

Other objects and advantages will appear in the 'following specification, and the novel vAn `insulating"liningfior strip 5` is *provided on the vertical face .ofthe lrabbeted 3 and J is farranged to :extend do-wn portionon the'sidewalls 4 of'the frame l.

The material 'of which the insulating strip is 'constructed-1s' similari to the ordinary weatherstripping. 'Bo-th4 walls of the rabbeted rportion 2 lai.e"provided with weather stripping 6 (see Figure 4).

hingedly "mounted nAninnerwor; glass bearing frame 7 is 'at 8to the frame l. Three walls ot this `frame 7 are arranged to `abe received 7inthe `rabbcted portions 3 of 'theltop wall ofthe sash iframe 1 'andthe rabbeted'portions on the sidewalls 4 yand vtobearagainst'the weather stripping prof Avided on` these 1 walls, whereby a lwaterT -tightseal is Aeffected and they frame 7 is 'pressedwintox close engagement 'with the -weatlier stripping to "preclude ltheV passage of water between the abutting parts of the frames l and A glass pane 8 is supported within the fra-me 7 by any suitable means such as em-V ployed in the ordinary y type of window sash. The window frame 7 has an angular downwardly projecting portion 9 on its lower and outer edge which is arranged to be received in the rabbeted portion 2 and to bear against the insulating strips 6. This structure effectively prevents the passage of water from the outside of the frame to the inside between the frames 1,7and 7.

Means for locking the frame 7 into close engagement with the fram-ev 1 is provided in a pair of locking members 10, one of which is clearly illustrated in Figure 3. These locking members consist each in a threaded spindle 11 having a collar 12 disposed int-ermediate the length of the spindle and a key portion 13 at the outer. end. The key portion 13 is pro-vided with a hingedly mounted finger grip member 111 which is normally folded in a plane transiferse to the axis o't' the spindle 11 (see Figure 1) but is capable of being hinged outwardly to vthe position shown in dotted lines in Figure 3 when in use.

A metal case 15, open at its outer end, is disposed concentric with the spindle 11 intermediate the collar 12 and the key 13. This case 15 is disposed in a depression 16 provided in the outer face of the upper wall of the frame'7.

The threaded portion 17 of the spindle 11 is arranged to project beyond thevouter face of the upper wall of the frame 7 and an interiorly threaded sleeve 18 is carried by the frame 1 at'the inner face of its upper wall, that is, the rabbete'd portion 3, in registration with the spindle 11. The tubular sleeve 18 is provided with a radially dis-V posed flange 19 at its outer endl by means of which the tubular portion 18 may be securely 'iXed to the frame 1 by means of screws 20 and the like.

Means for limiting themovement of the frame 7 on its supporting hinges 8 relative to the frame 1 is provided in a pair of rigid metal straps 21 pivotally fixed to one another at 22 and having' their outer ends pivotally mounted with the frame 7 and the frame l, respectively, as shown lat 23. y

A recess 24 is provided in the outer side walls of the frame 7 to accommodate thel straps 21 when the frame 7 is in the position shown in Figures 1 and 2.

From the foregoing description of the various parts of the device, the operation thereof may be jreadily understood. Let us assume that a window sash'of the character shown in Figure 1 has been used for someV Vtime and that it is desired to clean the winvdow. pane 8 therein. In order to accomplish this it is merely necessary to Vmove the hand grip portions 14 of the keys 13 into the position shown in dotted lines in Figure 3 and to rotate the keys 13`in a counter clockwise direction so that the spindle 11 also turns in a counter clockwise direction. As this is done, the tubular sleeves 18 will be forced outwardly relative to the threaded portions 17 which will result in the movement of the frame 7 outof engagement withthe frame 1, i. e., movement of the frame 7 on its sup- -degrees from the frame 1 on its supporting hinges 8. This movement of the frames 7 will permit ready access to the outer side of the window pane 8 so that it may be washed or otherwise cleaned by a person within the room, making it unnecessary to raise the sash and to sit on the window or to stand on the outside of the window as in the case of the ordinary sash'. Y

It will be noted that when the frame 7 is moved into the position shown in Figure 1, and the spindle 11 turned in a clockwise direction, the frame 7 is drawn'into watertight engagement with thel frame 1, whereupon moisture from the outside Vot' the window is kept out.

My improved window sash may be moved longitudinally in the Awindow frame justas Vany other window sash, and where two sashes are employed vin a window, each sash is constructed Vin accordance with the fore- CTI goingspecilication and the sashes are low-- ered alternately for cleaning.

I claim: A lock for securing the hmgedly mounted inner frame of a window sash against movement relative to said sash, comprising sockets carried by said sash iframe, threaded bolts having` thumb grips, rotatably mounted in said inner framefa'nd arranged to lie entirelywithin the lateral bounds oi said .inner and said sash frame when said' inner frameis closed, the threads thereof being arranged to engage with the threads of said sockets whereby said inner frame will be drawn into close engagement with said sash frame when said bolts are rotated.

WILLIAM STRANG.
